IMPROVEMENT `IN SHADES FOR GAS-LIGHTS.

Specification forming part of Letters Patent No. 103,865, dated June '7, 1870. I

To all whom it may concern:

Be vit known that I, WILLIAM: FULLAGAR., of Brooklyn, in the county of Kings and State ot' New York, have invented a new and useful Improvement in Shades for Gas-Lights; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification. l

My invention relates to bottom shades for gas-lights; and consists in an improved article formed of solid porcelain, with an upwardly-projecting annular flange around its extreme edge to hold the ordinary side shade in place. The said improved shade'may also be used with lamps, with slight changes in adaptation to the brass rings or supports, and is applicable, without change of the formrepresented, to what are known as the student lamps.77

The drawing represents a sectional elevation of a shade constructed and arranged ac cording to my improvements.

A represents my improved porcelain-bottom shade, consisting of a broad disk of porcelain, with a raised rim, B, at the outer edge, and a large hole in the center, around which is a downward-projecting ilange, C, for resting on the brackets D, attached to the burner, p

for holding the shade.

but the addition of the brass rims makes them too expensive, as the brass has to be milled over the edge of the disk to be secured thereto. I do not therefore claim a horizontal shade for the light thrown downward, broadlyT 5 but I do claim and desire to secure by Letters Patent- An improved. bottom shade, A, formed of'- porcelain in a single piece, upwardly iianged at B and downwardly iianged at C, each as and for the purpose specified.

The above specification of my invention signed by me this 13th day of April, 1870.
